Very basic (I think) wiring problem

    I'm trying to teach myself how to swap out pots and tone caps and just do general soldering work.

    I made a lot of rookie mistakes but now I'm getting good connections. And I'm getting a good strong signal from the pickup.

    The problem is the volume taper or lack of taper. 10 - 8 is acting correctly 8 - 0 is all silence. This is the 3rd pot I've tried with the same result. Gibson CTS and Alpha

    Obviously I'm making a basic error. Can anyone steer me in the right direction? Have you seen this problem before? Any connection in particular I should look at closer?

    thanks

    Are you using the right value of pot? Sounds like you're using a very low value pot.

    Get a multimeter, a.k.a. volt-ohm meter, a.k.a. DMM for digital multimeter. They're available for less than ten dollars, and are indispensable for electronics troubleshooting. I always try to confirm a part's value with a DMM before I install it, part of my "measure twice, saw once" philosophy.

    Don't know what a log pot is, but I'll look into that.

    These are the pots I'm using right now. 500k and I tried a 1meg.

    The multimeter sounds like a good idea though.

    Pardon me for getting this back to the top again.

    Has anyone heard of this problem before?

    The fact that three pots from 3 different makers are doing the same thing is making me rule them out as a cause.

    It's either my fault or the pickup.

    Any thoughts would be appreciated. This is frustrating.

    thanks

    Can you post a pic of your wiring.

    Yeah that's a good idea.

    The whole thing is apart now (I'm routing for a second pickup).

    When I get it back together I'll post a pic.

    Yeah I looked into it also, all 3 pots were audio taper.
